装填機能を備えた操作性の良い用紙巻取装置の実用化が
かねてから要望されている。This operation may be performed several times a day, such as when the paper is used up and a new one is loaded, or when the paper jams and the paper is reloaded. There was a lot of fear. For this reason, there has long been a desire to put into practical use a paper winding device with good operability and an automatic loading function that automatically winds the paper around the winding shaft when loading the paper.

囲に広いスペースをとる必要があった。A paper winding device with an automatic loading function that has already been put into practical use consists of a rubber sleeve in which the paper winding section of the winding shaft is divided into multiple segments, and a coil spring is wrapped around the rubber sleeve. With conical clamps placed on both end faces of the paper and tightened in the axial direction to enlarge the shaft diameter, the winding start end of the paper guided by the winding guide member is pulled by using friction with the rubber sleeve. There is one that is wound around the take-up shaft. With this device, the friction between the rolled paper and the rubber sleeve is too great to remove the rolled paper as it is, so the rubber sleeve is untightened by the clamp and the shaft diameter is adjusted. Paper is extracted in the reduced state, but after paper is removed, it takes time to return the reduced shaft diameter to its original state and make it ready for winding. It was necessary to provide a large space around the winding shaft.

１４ｄで押圧された用紙２と第１の部分４ａの接触面の
間の摩擦力によって得られる。This is obtained by the frictional force between the contact surface of the paper 2 pressed at 14d and the first portion 4a.
摩擦の法則によれば、２物体の接触面に生じる摩擦力の
大きさは接触面の垂直荷重と摩擦係数の積で決定され、
接触面積の大小にはよらない。According to the law of friction, the magnitude of the frictional force generated on the contact surfaces of two objects is determined by the product of the normal load on the contact surfaces and the coefficient of friction.
It does not depend on the size of the contact area.

なことがわかる。From this, in order to prevent paper from slipping, it is not necessary to make the entire paper winding section of the winding shaft made of rubber as in the conventional example, and instead, as in this embodiment, a part of the paper winding section 4a is made of rubber. It can be seen that it is sufficient to make only the paper from a material such as rubber that has a relatively large coefficient of friction with the paper, and to press the paper against this part.

Figure (a) shows the state in which the paper 2 is wound on the winding shaft l, and Figure 5 (bl is a diagram showing the state in which the detachable part 4c at one end of the winding shaft is pulled out. All you have to do is put your finger into the hollow part 21 left after pulling out the part 4°, grasp the rolled paper 2 from the inside and outside, and pull it out from the winding shaft l. Most of the rolled paper 2 is Since the second portion 4b of the winding shaft has a relatively small coefficient of friction between the winding shaft and the winding shaft, the winding shaft can be easily removed.

用紙抜取りの可能なことが実験により確認された。In this embodiment, the outer diameter of the first portion 4a, which has a relatively large coefficient of friction with the paper, is made smaller than the outer diameter of the second portion 4b, which has a relatively small coefficient of friction with the paper, and the paper is removed. However, even if the outer diameters of the first portion 4a and the second portion 4b are the same, the ratio of the first portion 4a to the entire paper winding portion is Because it is small, paper removal is not obstructed. In particular, when the structure is such that the finger can be placed on the inside of the rolled paper as in this embodiment, the circumferential surface of the first portion 4a is connected to the second portion 4.
Even if it is partially higher than the circumferential surface of b,
Experiments have confirmed that paper extraction is possible.

填機能を備えた用紙巻取装置を実現できる。According to the present invention, the take-up shaft has a first portion having a circumferential surface having a relatively large coefficient of friction with the paper, and a circumferential surface having a relatively small coefficient of friction with the paper. Since a second portion is provided to press the paper between the first portion and a pressing portion provided on the winding guide member, the frictional force between the first portion and the paper is applied when loading the paper. It is possible to prevent the paper from slipping and ensure that the paper is wound around the take-up shaft.On the other hand, since the first portion occupies a small proportion of the entire paper winding section, when the paper is taken out, the paper is wrapped around the take-up shaft. It is possible to easily remove the wound paper from the winding shaft without changing the diameter, and it is possible to realize a paper winding device equipped with an automatic loading function that is highly reliable and easy to operate.
